HIGH-SPEED UNIPOLAR DETECTION TYPE HALL IC
© SII Semiconductor Corporation, 2013-2015
Rev.1.6_01
The S-57A1 A Series, developed by CMOS technology, is a high-accuracy Hall IC that operates with high temperature and
high-withstand voltage.
The output voltage changes when the S-57A1 A Series detects the intensity level of magnetic flux density. Using the S-57A1
A Series with a magnet makes it possible to detect the open / close and rotation status in various devices.
The S-57A1 A Series includes a reverse voltage protection circuit and an output current limit circuit.
High-density mounting is possible by using the small SOT-23-3 package.
Due to its high-accuracy magnetic characteristics, the S-57A1 A Series can make operation's dispersion in the system
combined with magnet smaller.
Caution This product can be used in vehicle equipment and in-vehicle equipment. Before using the product in the
purpose, contact to SII Semiconductor Corporation is indispensable.
